To all whom it may-concern:

Be it known that I, RUssEL G. WOOD- WARD, a citizen of the United States, residing at Waukegan, in the county. of Lake, State of Illinois, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a description, reference being had to the accompanyin drawing, and to the letters and figures of reference marked thereon."

V My invention relates to certain improvements in sewing .machines, and has for its principal object to construct a machine capable of forming both straight away and zig zag or over-edge stitches, in which the character of the stitch may be changed at the will that when the of the operator. I j

In Letters Patent granted tome on the 23rd day of February, 1904,-No.'7 53,187,'1 have shown, described and claimed a'ma chine of a similar type, and'the present invention consists in certain features of. construction and arrangement of operating parts, whereby the change from zig zagto straight-away stitching and viceversa, can only be accomplished while the needle is {de-' s'cending, and about to enter the goods, this being accomplished-l on the left, hand stitch when the zig zag' mechanismv is at work.

This machine, as well as the lnj'achine illus' trated in the aforesaid pat'ent,;was designed principally' for'nse in 'connection'withthe closing of the uppers of shoes at the rearportion, the object being to first sew the two superposed edges of theuppers together ,a

'short-distancebya' line of straight-away sew ing, and then bya line of zig zag stitches, so Eieces of leather are spread I out flat there wi be no'ridgeupon themside of the shoe, except at the'very .top of the rear part. The said. strip is then, applied in the usual manner overt e upper and counter of the shoe; The seam adapted to be sewed on this machine, forms the subject matter of another application filed October 30 1902, Serial No. 129,383.

In addition to the general object of the in- .vention above stated, further objects are to so construct and arrange the mechanism for changing the character of thestitch as to render it in great measure self-adjusting,so that any premature movement of that portion of the stitch-forming mechanism adjust-- ed may be revented, the movement at either change )eing so governed by the mechanism as-to at all times produce a perfect stitch 'at-the changing point.

Other objects are to so construct the apparatus that the change of stitchQmay be made by the operator by a single movement, without stopping the machine; to provide for the positive operation of the parts, and for the adjustment of the various parts of the mechanism, and the renewal of adjustment of those portions subject to the greater Wear.

The features of the invention made by me having been set forth in the former patent, the present invention comprises, in a some what restricted sense, certain improvements therein, adapted to bring the machine to a greater degree of perfectiomjbo'th in constructio'n' and mode of operation, or perhaps in one sense, the invention may be stated to consist in combining with an overseaming machine adapted to have a'zig z'ag movement imparted to the needle, mechanism for imparting such movement, with means for throwin thesame into and out of operation at thew ll of the operator, said means includinglockin devices which alternately act at the will 0 the operator, to hold in engagement or release from engagement the zig zag needle mechanism from its operative connectionsw'ith the driving shaft.

.Furthermore, the invention consists in combiningwith the usual zig zag mechanismof a sewing machine with a driving shaft for operatin it, of connections between the driving s aft and the z'ig 'zagmechanism, in.- cluding two locking devices operable at the will of thee erator, one of-wh'ich locks the zig zag mec anism tov the connections between-1t and the drivin shaft, and the other of which, as said ,first lo kjng device is thrown out. of action, operated to clutch the zig za mechanism and prevent any accidenta swinging of'the needle bar ateor frame.

The above statements 0 the features in-.

cluded in thepresent invention relate particularly to the application thereof to amachine of the special type-referred to, but 1t will be understood that so far as the feature "of throwing into and out of operation a mechanism or member is concerned, the invention maybe apphcable to other uses, where It ls'desired to "sus endat desired intervals and at the will of t e operator, the action of somepart of the machme, as for example, a

The

On said shaft B is secured a pinion .23 on the frame G, and prevent movement of F, the teeth of which intermcsh with those of the part 22, except when thecam or eccentric.

f is in a certain position, this being timed so that the cam wi only assume'this position as the needle is just about to enter the goods in its descent.

- As above stated, by adjusting the stud 3- -u'p.or down the curved-slot 1, the amount of' lateral throw of the needle is varied. In adjusting this thepivoted frame 8. is also adjusted and it is necessary also to adjust automatically the plates 12 and 13, which engage the piny on the-under side. This is done by the curved slot 6, which Whenthe stud 3 in the slotted segment is thrown up to the top,

throws the pin 11, in thecurved slot, toward; 5 the front of the machine, thus adjusting the cut-out portion of the frame 8 to meet the pin 7'- that the machine will sew straight-away, but,

when the lever 25 is pulled downwardly, then the parts are shifted to cause the pivoted frame 8 to engage the pivot pin 7', and then oscillatory movement will be imparted to the rock shaft, and, therefore, the zig zag movement to the needle.

Assuming the arts to be in the position shown in F g. 2, t e pin is locked in the recesses c in the plates '12 and '13, so that no swinging of the needle bar. gate or frame can take place, the pivoted member or frame 8 is out of engagement with the pin 1', and the usual strai ht-away sewing is accomplished on the mac ine.

40 The bar K by reason of the slot 5 therein slides back and forth with respect to the pin 1'. To shift tozigzag sewing, the operator pulls down upon the lever 25 which tilts the cam plates 12 and 13, moving down the slide 21.and forcin the pivoted frame 8 into en- 'a ement wit the pinvj; when the frame 8 1s ooked to the pin 1 then the reciprocatory motion of the bar K is transmitted to the arm J, thus oscillating the rock shaftJ, and

through it impartin lateral movement to the needle. It will be understood that the pivoted'frame 8; cannot be forced entirely mto en a ementwith the pin-(i, until cam has pull e the projection 23, out of line with projection 22, .which ha pens when the needle is onits descent ans about to enter the goods. The purpose of the above arrangement is obvious. It is necessary that the needle should be positioned in line with the straight-away stitch when the vibrations 'thereof are rendered ineffective, so that in the continued reciprocation of theneedle the stitches will be roperly placed within the fabric. If, thereore, the needle is making the overedge stitch, that is, reciprocating beyond the edge of the fabric, and the vibrating mechanism should be thrown out, the needle would have to be moved-laterally, and if below the fabricthe same' would be sprung or broken. By my improvement, wherein a sto prevents the throwing out except whentie needlepoint is above the lane of the upper surface of the fabric, or

1n line for the straight-away stitchin the above objection is avoided. It will a so be 75 noted that the stop revents the throwing in of the vibrations w en stitching straightaway except when the parts are properly positioned. The width of the-zig zag line of stitching may be regulated by adjustment 30 of bolt or stud 3 in curved slot 1.

In practice it has been found desirable to use a cam f of the shape shown. This three cornered cam gives the necessary time for the change from one style of stitchingto the 35 other, as the fork is at rest between the points on theeccentric marked'with-stars. All the switching of the mechanism takes place while the eccentric moves from one star to the other.

It will be noticed that on this machine the needle 'unctures inthe material will be all in a de ed line that is, all the needle punctures both straight-away and upon one side of the zi zag, are in a strai ht line, which is 5 absolute y necessarywhen t e seam has tobe opened out. -It would not do, to have. the line of straight-away stitches in a line with the center of the zig zag stitches," as an abru t spot in the back. of the shoe would re- 1 su t. Thiscan only beaccompl-ished by hav ing all the lateral movements of the needle bar take place while the needle-is above the throat plate of the machine. I The system of levers shown in' certain figures of the drawing between the lever- 25, and the feed rocker is for the purpose of regulating automatically the length of the zig zag stitches to correspond to the length of the straight away stitches. This mechanism, 1 while a part of the machine, does not form a part of the subject matter of this application, it being the invention of Lansing Onderdonk, and forming the subject matter of an application filed by him November 4, 1902, Serial No. 130,038.

It will be understood that various minor modifications and changes in the construction of the parts of this machine may be made, without departing from the spirit of.

the invention.
